# P800 Long-Context Matrix for DeepSeek-V4-Flash-INT8

Long-context throughput/latency matrix for SGLang-XPU on Kunlun P800 (8x XPU).

## Scope

- Model: `DeepSeek-V4-Flash-INT8` (W8A8 INT8)
- Backend/engine: `sglang-xpu`
- Hardware: 8x Kunlun P800 XPU
- Input lengths: 64k, 128k
- Output lengths: 256, 1024, 4096
- Concurrency: sweeps per context group (see `config.env`)

## Usage

```bash
cd /data1/yy/sskj/experiments/dsv4_p800_long_context_matrix
bash run_bench.sh
```

Optional environment overrides:

```bash
PORT=30013 RUN_ID=myrun bash run_bench.sh
```

## Outputs

Results are saved under `results/${RUN_ID}/`:

- `raw_outputs/`: raw `sglang.bench_serving` JSONL files
- `report.md`: parsed per-scenario metrics
- `results.json`: structured metadata + scenarios
